SHANK FOR CORNETS.

SPECIFICATION forming part of Letters Patent No. 629,254, dated July 18, 1899.

Application filed January 30, 1899. serial No. 708,850. (No model.)

To all 1.0700112 it may concern:

Be it known that we, WILLIAM HENRY HORN, of San Francisco, in the county of San Francisco and State of California, temporarily residing in Kamloops, in the Province of British Columbia and Dominion of Canada, and CHARLES LEWIS WAIN, of Kamloops, in the Province of British Columbia and Dominion of Canada, have invented a new and Improved Shank for Cornets and Like Musical Instruments, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved shank for cornets and I 5 other similar brass instruments and arranged to permit the performer to set the instrument to different keysfor instance, to B fiat or A natural, or vice versa-in a very simple manner and without requiring separate shanks of different lengths.

The invention consists of novel features and parts and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.

A practical embodiment of our invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in both the figures.

Figure 1 is a sectional side elevation of the improvement as applied to a cornet, and Fig. 2 is a like view of the same with parts in a different position.

The shank for the cornet or like musical 3 5 instrument is made in two sections A and B,

of which the section A is adapted to be secured to the body C of the instrument and the other section B is arranged to carry a mouthpiece D, as is plainly indicated in the drawings. The section B is arranged to telcscope in the section A, and the latter is provided at its outer end with a head E, screwed or otherwise fastened in place and formed on the inside With threads E, adapted to be e11- 5 gaged by external threads B and B formed on the section B, near the ends thereof, as is plainly indicated in the drawings. A handle B is formed on the section B at the outer side of the threads B to permit the operator to con- 5o veniently screw the section B with either set of threads B or B in the internal. threads E of the head E.

When the several parts are in the position shown in Fig. 1, the threads B screw in the threads E of the head E, and the section B is 5 5 thus locked in a telescoped position in the body-section A. The cornet is now arranged for the key at B flat, and when it is desired to change the key to A natural the operator turns the handle B to screw the threads B out of the head E and then slides the section B outward to finally screw the threads B into the threads E to hold the mouthpiece'seo tion D in a locked extended position, as indicated in Fig. 2.

The inner end of the section B is provided with an annular shoulder B for preventing said section B from being accidentally screwed out of the head E.

From the foregoing it is evident that the performeris enabled to readily extend or close the shank to change the instrument from one key to another. It will further be seen that by the arrangement described the shank-sections are always firmly united with each other, 7 so that they cannot become separated, and thereby lost.

Having thus fully described our invention, we claim as new and desire to secure by Letters Patent 1. A musical instrument of the class described, provided with a shank made in sections, one of which is the hody-section and is provided with an internally-threadedhead and the other is provided with a monthpiece-section, and is arranged to telescope in the bodysection, the mouthpiece-section having two sets of screw-threads adapted to screw in said head, to hold the mouthpiece-section locked in either an extended or closed posit-ion, substantially as shown and described.

2. A musical instrument, having a shank made in two sections sliding the one within the other, the outer section having a head with internal threads and the inner section 5 having two external threads capable each of engaging with the threads of the head to hold the inner section in either one of two positions.
